For the revision of the genus Laserpitium for Flora lberica I have revised numerous materials of many herbaria. In this paper I present! the result of a morphological and taxonomic study of L. nestleri and L. eliasii, supported with numerous iIIustrations only partially included here. L. nestleri subsp. nestleri is distributed from Central France (Central Massif) to the SE of the lberian Peninsula. Two new subspecies allow to relate the morphological variability observed with their geographical distribution. L. nestleri subsp. flabellatum is found in the Pyrenees and Ihe Cantabrian mountains, and L. nestleri subsp. lainzii is a remarkable endemism located in the mountains of the N of Leon. L. eliasii also presents a great morphological variability. Their distribution area is overlapped partially with that of L. nestleri subsp. flabellatum. L. eliasii subsp. ordunae include forms located in the Basque country while the most western populations, from W Galicia and N of Portugal, belong to L. eliasii subsp. thalictrifolium. I propose different new varieties to highlight some remarkable local forms. The study of mericarp section. the distribution of estomate and the morphology of hairs and basal leaves are very useful for delimitate these taxa.
